Air Bubble Detection (ABD)
A Perfusion Screen can contain up to 4 air sensors.
It is recommended that an ABD system be used on the arterial line for every case.
There are three air sensor sizes. The 3/8 in. x 3/32 in. sensor (red) will detect air
bubbles of 0.5 cc or larger at flow rates up to 6 L/min for 3/8 in. tubing. The 1/4 in. x
3/32 in. sensor (gold) and 1/4 in. x 1/16 in. sensor (black) will detect air bubbles of 0.3
cc or larger at flow rates up to 3 L/min for 1/4 in. tubing.
The ABD detects air bubbles within clear, flexible medical grade PVC tubing
in clear priming solutions or blood with hematrocit from 15% to 40%.
WARNING: The level detection and air bubble detection systems must be
properly set up and turned ON as UNDETECTED AIR in the line may cause
gaseous emboli to be pumped into the patient, with attendant risk of DEATH
OR SEVERE INJURY. The performance of the level and air detection must be
verified before each use.
WARNING:
If an air or level detection system is turned OFF or is configured
not to stop a pump, then constant monitoring is required to reduce the risk of air
embolism in the line.
WARNING: If the cardioplegia pump is drawing blood from the arterial line, stop
the cardioplegia pump whenever the arterial pump is stopped to avoid infusion
of air.
Connect ABD Module
1. Select the sensor which is appropriate for the tubing size to be used.
2. Ensure the sensor is clean, free of debris, and undamaged.
3. Align red dots on the sensor cable and module receptacle and insert cable into
module. Pull gently to check the connection.
4. Insert ABD module into base receptacle as close as possible to the location
where the sensor will be used. Arrange cables to minimize exposure to spills.
Red Dots
WARNING: The air sensor may not detect air bubbles smaller than the
minimum size specified for the air sensor used. The air sensor must be
used with the appropriate tubing size and within the flow rate limitations
specified for the air sensor or the air sensor may not detect air bubbles.
